Auto Configure Connected Anchor seems completely broken . Tested on 6000.2.0b2. As soon as you hit play completely erroneous numbers are shown for Connected Anchor. I have a chain and on previous versions I had values of close to zero as you would expect. Now I am getting numbers in the hundreds.

I'd like to add that enabling domain/scene reloading does fix the connected anchor not calibrating when entering play mode, but the gizmo still shows the last location until entering play mode.
Also noting that this also affects SpringJoint components.
Thanks!

Resolution Note:
Hello!
AutoConfigure connected anchor doesn't constantly check if the connected rigid body's position has changed. It is instead a snapshot of the anchors position when the joint initializes with the checkbox on. If you desire to update the anchor dynamically please specify it manually by setting the new value using the Joint.connectedAnchor property.
We will take the feedback from this case and see how we can further improve the feature going forward.
Cheers,
AlexRvn.
